Overview
This Spinach and Feta Egg White Omelet is a light yet satisfying dish that highlights clean flavors and simple technique. Tender egg whites form a soft, delicate base, while sautéed spinach adds freshness and feta brings a salty, creamy contrast. It is high in protein, lower in fat than a whole-egg omelet, and ideal for breakfast, brunch, or a quick, healthy meal any time of day.
Ingredients
For the Omelet
- 1 cup liquid egg whites (or whites from 6 to 8 large eggs)
- 1 teaspoon olive oil or butter
- 1 small clove garlic, finely minced (optional)
- 2 packed cups fresh baby spinach
- 1/4 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper
- 1/4 teaspoon dried oregano or Italian seasoning (optional)
- 1/3 cup crumbled feta cheese
Optional Add-Ins and Toppings
- Diced tomato
- Sliced green onions
- Red pepper flakes
- Fresh herbs such as dill or parsley
Step 1: Prepare the Spinach Filling
Heat a nonstick skillet over medium heat. Add half of the olive oil or butter.
If using garlic, add it to the pan and cook for about 20 seconds until fragrant. Do not let it brown.
Add the spinach and a pinch of salt. Cook, stirring frequently, for 1 to 2 minutes until the spinach is fully wilted.
Transfer the spinach to a bowl and gently press out any excess moisture using the back of a spoon or a paper towel. Set aside. Removing excess liquid helps keep the omelet from becoming watery.
Step 2: Prepare the Egg Whites
In a bowl, whisk the egg whites with salt, black pepper, and oregano if using. Whisk just until combined and slightly frothy. Avoid over-whisking, which can make the omelet dry.
Step 3: Cook the Egg Whites
Return the skillet to medium-low heat and add the remaining olive oil or butter, spreading it evenly across the pan.
Pour the egg whites into the skillet. Let them cook undisturbed for 1 to 2 minutes until the bottom is set and the top is just beginning to turn opaque.
Using a spatula, gently push the cooked edges toward the center, allowing any uncooked egg white to flow to the edges. This promotes even cooking without browning.
Step 4: Add the Filling
Once the egg whites are mostly set but still slightly glossy on top, evenly scatter the cooked spinach over one half of the omelet.
Sprinkle the crumbled feta cheese over the spinach.
Cover the pan with a lid and cook for another 1 to 2 minutes until the egg whites are fully set and the feta is just softened.
Step 5: Fold and Finish
Carefully fold the omelet in half using a spatula.
Cook for an additional 30 seconds, then slide the omelet onto a plate.
Step 6: Serve
Serve immediately while warm.
This omelet pairs well with whole-grain toast, sliced avocado, fresh fruit, or a simple side salad.
